cooling fan inlet) of less than 10 C. In case your expected Trise is grater than 10 C a correction factor
should be used as explained below. For each 1 deg C Trise above 10C, the correction factor CF is defined as
CF= 1.7 / Processor_TDP.
2. Example, For A Chassis Trise assumption of 12 C for a 95W TDP processor.
CF = 1.7/95W = 0.018/C
For Trise > 10 C
CA at Tcontrol = Value listed in Column_2 - (Trise - 10) * CF
CA = 0564 - (12 - 10) * 0.018 =0.528 C/W
In this case the fan speed should be set slightly higher equivalent to YCA=0.528C/W
